I was getting annoyed today by lousy spreads on illiquid contracts. Fantasized about manipulating prices, but... 1. It is a violation of U.S. option exchange rules for a customer, acting alone or in concert with others, to send an order to an option exchange in order unlawfully to manipulate the execution price of a separate order on that exchange or on another exchange. (From IB's Forms and Disclosures) This is common knowledge, but I am in the mood to complain. I'm sure most of you find the rule to be complete bullshit (along with the five or so others that I did not include here). Hopefully, IB's venture with BOX will put an end to this: Nowadays, if one puts in a relatively small order (10 contracts or less) your order is automatically pegged by MM's on options exchanges who will display more size at the same price, effectively sending the small order to the back of the line, and voiding any chance to buy the bid or sell the offer. This is 'legitimized' by the above rule, legally obligating a retail trader/investor type to cough up the spread. BOX, however, is intended to give everyone equal footing- http://www.elitetrader.com/vb/showthread.php?s=&threadid=4100l My question is this: how is BOX going to actually put an end to this practice, considering that there are at least 5 other exchanges that currently have all market share...? Also, will BOX use price increments of 0.05, or will there be a move to go to 0.01? (Using the smaller decimal increment might give BOX the edge it needs). PLUS, (fitting in with their overall theme of screwing you however they can) options MM's give hefty payment for order flow - I hardly see BOX competing in this respect (at least initially), not to mention the difficulty for the generic retail brokers (i.e. datek, fidelity, etrade) to gear up in order to route to BOX. Any thoughts?
